\*Elderly:\* dosage reduction may be required.4.3 Contraindications
Aciclovir tablets are contraindicated in patients known to be hypersensitive to aciclovir, valaciclovir or to any of the excipients.4.4 Special warnings and precautions for use
Hydration status:
Care should be taken to maintain adequate hydration in patients receiving high oral doses of aciclovir.
Use in patients with renal impairment and in elderly patients:
Aciclovir is eliminated by renal clearance, therefore the dose must be reduced in patients with renal impairment (see section 4.2). Elderly patients are likely to have reduced renal function and therefore the need for dose reduction must be considered in this group of patients. Both elderly patients and patients with renal impairment are at increased risk of developing neurological side effects and should be closely monitored for evidence of these effects. In the reported cases, these reactions were generally reversible on discontinuation of treatment (see section 4.8).
Prolonged or repeated courses of aciclovir in severely immune-compromised individuals may result in the selection of virus strains with reduced sensitivity, which may not respond to continued aciclovir treatment.
Aciclovir should also be used with caution in patients with underlying neurological abnormalities, severe hepatic or electrolyte abnormalities or significant hypoxia.
Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.4.5 Interaction with other medicinal products and other forms of interaction
No clinically significant interactions have been identified.
Aciclovir is eliminated primarily unchanged in the urine via active renal tubular secretion. Any drugs administered concurrently that compete with this mechanism may increase aciclovir plasma concentrations. Probenecid and cimetidine increase the AUC of aciclovir by this mechanism, and reduce aciclovir renal clearance. Similarly increases in plasma AUCs of aciclovir and of the inactive metabolite of mycophenolate mofetil, an immunosuppressant agent used in transplant patients have been shown when the drugs are co-administered. However, no dosage adjustment is necessary because of the wide therapeutic index of aciclovir.
The risk of renal impairment is increased by the concomitant use of other nephrotoxic drugs.
\*Antivirals:\* fatigue has been associated with the combined use of aciclovir and zidovudine.
Aciclovir may increase serum theophylline levels.4.6 Pregnancy and lactation
\*Pregnancy\*
The use of aciclovir should be considered only when the potential benefits outweigh the possibility of unknown risks. A post-marketing aciclovir pregnancy registry has documented pregnancy outcomes in women exposed to any formulation of aciclovir. The registry findings have not shown an increase in the number of birth defects amongst aciclovir exposed subjects compared with the general population, and any birth defects showed no uniqueness or consistent pattern to suggest a common cause.
\*Lactation\*
Following oral administration of 200mg aciclovir five times a day, aciclovir has been detected in breast milk at concentrations ranging from 0.6 to 4.1 times the corresponding plasma levels. These levels would potentially expose nursing infants to aciclovir dosages of up to 0.3 mg/kg/day. Caution is therefore advised if aciclovir is to be administered to a nursing woman.4.7 Effects on ability to drive and use machines
The clinical status of the patient and the adverse event profile of aciclovir should be borne in mind when considering the patients' ability to drive or operate machinery.
There have been no studies to investigate the effects of aciclovir on driving performance or the ability to operate machinery. Further, a detrimental effect on such activities cannot be predicted from the pharmacology of the active substance.4.8 Undesirable effects
The frequency categories associated with the adverse events below are estimates. For most events, suitable data for estimating incidence were not available. In addition, adverse events may vary in their incidence depending on the indication.
The following convention has been used for the classification of undesirable effects in terms of frequency: very common ≥ 1/10, common ≥ 1/100 and <1/10, uncommon ≥ 1/1,000 and <1/100, rare ≥ 1/10,000 and <1/1,000, very rare <1/10,000, not known (cannot be estimated from the available data).

Not known: Renal impairment
Renal impairment is usually reversible but may progress to acute renal failure
\*General disorders and administration site conditions\*
Common: Fever, fatigue
\*\*Reporting of suspected adverse reactions\*\*
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard4.9 Overdose
\*Symptoms and signs\*
Aciclovir is only partly absorbed in the gastrointestinal tract. Patients have ingested overdoses of up to 20g aciclovir on a single occasion, usually without toxic effects. Accidental, repeated overdoses of oral aciclovir over several days have been associated with gastrointestinal effects (such as nausea and vomiting) and neurological effects (headache and confusion).
Overdosage of intravenous aciclovir has resulted in elevations of serum creatinine, blood urea nitrogen and subsequent renal failure. Neurological effects including confusion, hallucinations, agitation, seizures and coma have been described in association with overdosage.
\*Treatment\*
Patients should be observed closely for signs of toxicity. Haemodialysis significantly enhances the removal of aciclovir from the blood and may, therefore, be considered a management option in the event of symptomatic overdose.
- Instruction Pharmacology
- 5.1 Pharmacodynamic properties
The antiviral activity of aciclovir is due to intracellular conversion to an active form that inhibits viral DNA synthesis and replication by inhibiting the herpes virus DNA polymerase enzyme as well as being incorporated into viral DNA. Herpes simplex virus type 1 appears to be the most susceptible, then type 2, followed by varicella-zoster virus.
The Epstein-Barr virus and cytomegalovirus are also susceptible to aciclovir to a lesser extent.
Aciclovir has no activity against latent viruses, but there is some evidence that it inhibits latent herpes simplex virus at an early stage of reactivation.5.2 Pharmacokinetic properties
Aciclovir is slowly and poorly absorbed from the gastrointestinal tract and the time taken to reach peak concentrations is 1.5 to 2 hours. With multidose administration, steady-state plasma concentrations are achieved by the next day. Bioavailability is 13 to 21% and appears to decrease with increasing dosage. In adult patients with normal renal function the plasma half-life is 3.3 hours.
Aciclovir is widely distributed in tissues and body fluids including brain, kidney, lung, liver, muscle, spleen, uterus, vaginal mucosa, vaginal secretions, cerebrospinal fluid and herpetic vesicular fluid. Concentrations in kidney and lung were 10 to 13 times those of plasma concentrations after multiple dose therapy and 25 to 70% of the plasma level was found in the brain, spinal cord and cerebrospinal fluid. Limited human data show that aciclovir passes into breast milk and levels can be three to four times higher than in serum.
Aciclovir persists in the plasma of patients with renal insufficiency and the mean terminal plasma half-life recorded in patients with end stage renal disease is 19.5 hours. Aciclovir is readily removed by haemodialysis.
In infants of less than three months of age, the plasma half-life is slightly prolonged to about 3.8 hours and clearance is about one third of that found in older children and adults. In neonates (0 to 3 months of age) treated with doses of 10 mg/kg administered by infusion over a one-hour period every 8 hours the Cssmax was found to be 61.2 micromolar (13.8 microgram/ml) and the Cssmin to be 10.1 micromolar (2.3 microgram/ml). A separate group of neonates treated with 15 mg/kg every 8 hours showed approximate dose proportional increases, with a Cmax of 83.5 micromolar (18.8 microgram/ml) and Cmin of 14.1 micromolar (3.2 microgram/ml).
The pharmacokinetics of aciclovir in children over one year old seem to be similar to those of adults.5.3 Preclinical safety data
There are no pre-clinical data of relevance to the prescriber that are additional to those included in other sections.
